Specification of Letters Patent. Application mea April 11,1907. serai No. 367,544..

Patented Aug. 2:5, 190s.

To all whom it may concer/n:

,Be it known that we, YJULIUs WEGNER, a subject of the Czarof Russia, residing at borough of Queens, county of Queens, and State of New -York, and WIL-` LARD F. MEYERS, a citizen of theUnited States, residing at Long Island City, borough of Queens, in' the county ofQueens and State of New York, have invented a certain new and useful Improvement in Stone-Sawing Machines, of which the following is a specification, reference being had therein-to t e accompanying drawings, forming a part thereof.

Our invention relates particularly to machines for dividing rough blocks of stone and for rough-dressing them or finishing them according to the character of the work.

The object of the invention is to produce a machine in which a great variety of operations may be performed with a minimum expenditure of time in adjusting themachine and settingup the work, and to this end the machine'is provided with means for adjusting the saws both angularly and laterally, and with means for feeding the saws in two directions at fast or slow speed.

Certain Yminor details of construction resulting in improved operation and facility in construction of the machine are also hereinafter described. i r

We will now describe the construction embodying our invention shown inthe accompanying drawings, and will thereafter point outour invention in claims.I 1

Figure 1 is aside elevation of a stonesawing machine embodying the resent invention. '.Fig. 1a is an enlarge sectional detail onthe line4 1iL of Fig. 1. Fig. 2 is a plan view, artly in section, of the machine, the drivin motorr bein omitted.

' Fig. 3 is a sectiona elevation of t e machine `on the lines 3 3, Figs. 1 and 2, looking from left'to right. Fig. 4 is a plan View, partly `1nsection, of the saw carriage andsaws and their adjustable connections. Figs. 5 and .6 are'er'l elevations of the saws and the vsaw carriage, .showing the saws vin differently adjusted-positions, looking from left'to right of the machine as re resented in the preced- Ing figures.' Fig. 7 1s afplan view, partly in l section, showing details of the feeding mechanisms. Figs. 8,9, A10, 11 12 and '13 ,are diagrammatlcvlews showing various loperations which may be performed by the saws,

`yokes are journaled in turn on sleeves 5,

' en aging a bevel i The illustrated-embodiment of theinvention comprises two rotary saws with means for actuating' them, means for supporting the saws having provision for both angular and lateral adjustment of the saws to determine the character of the operation on the stone, slow-feeding mechanism for feeding the saws during their o eration, and

uic feeding or moving mec anism to fadilitate the preliminary operation of bringing the saws into working position.

The saws, 1 and 2, are mounted on short shafts 3 journaled in yokes 4 (Fig. 4). The

projecting from the ends of supporting arms 6 journaled on sleeves 7 projecting from, and integral with, the saw carriage 8. The yokes 4 and arms 6 constitute adjustable connections Abetween the saws and the carriage, for by reason of the yokes being swiveled on the arms the saws may be adjusted angularly `with relation to each other and the Work while by reason of the arms being swung or pivotcd on'the carriage thesaws may be adjusted laterally and the distance between their peripheries vmay be adjusted. The yokes 4 ,are held in adjusted position by bolts 9 engaging annular T-shaped slots in the yokes. To yeffect the angular adjustment ofthe saws, means are rovided for adjusting the yokes when the bo ts are loosened, these means comprising Worm wheels 11 fixed to the yokes and worms 12 journaled on the A arms 6 and provided with squared extremities for the reception of a wrench, as shown in Fig. 5.

To effect the ylateral adjustment of the saws, means are provided for adjusting the arms 6. On each arm is journaled a shaft 13 having a squared extremity 14 to receive a wrench. The shaft carries a bevel gear 15 gear 16 fixed on a screw 17 (Figs. 5- and 6). -The'screw is journaled at one end in'a swivel sleeve 18 pivotally connected with the arms 6 concentricallyA with the axis of the shaft 1,3, and a collar or head f Jtween the extreme positions shown in Figs.

A5 and 6, thlis effecting lateral adjustment of Tthe saw.l lTo hold thearms rigidly in adl the frame as shown,

'l .vating screws 43 supported on a column 44 2 see,

justed position, their ends are split and ro- .vided with clamp1bolts23by which t ey` may beclamped upon the sleeves 7. y To actuate the saws the saw wshafts 3 are provided with bevel gears 24 engaged by gears 25 on counter-shafts 26 journaled at one end in the arms 6 and atth'e other in brackets 27 mounted on the arms. Pulleys 28 lon the counter-shafts are connected'by belts with pulleys 29 fixedA on the vends of a a sleeve 31 journaled in the sleeves 7 on the carriage. A driving shaft 32, journaled in assesthrough the sleeve 31 and is splined t ereto, as shown, so that the saws may be actuated without regard to longitudinal' movement of the carriage with respect to the driving shaft. L It is evident that the arrangement of this saW- actuating mechanism is such that its operationis not disturbed by changesin the adjustment of the arms 6 and the yokes 4.

The saw-feeding mechanism-isarranged to feed the saws. both horizontally and vertically. 'To permit horizontalmovement the carriagev 8 is suspended by gibs 33, from ways on av horizontal frame 34 along which thecarria e slides. A nutl 35 on the carriage A is engage by a horizontal feed screw 36 by fwhich the carriage is horizontally actuated or fed.

Vertical feeding movements of the saws are accomplished by moving the frame 34 vertically as a whole. A rotatable lifting nut 37 at thel right-hand end of the frame, 3'5 as illustrated, engages a stationary elevating screw 38 which is supported on a column 39. To guide the frame in its vertical movements the column is provided, as shown in Fig. 2,- 'With dove-tail ways `engaged by dove-tail gibs 41 on the frame 34. Near the left-hand end of the frame are two rotatable lifting nuts 42 (Fig. 3) engaging two stationary elewhich is en aged b gibs 45 on the frame 45 (Figs. 2 and 7). T e weight of the frame and the mechanismsA carried thereby is supported by the screws 38 and 43, the rotatable y nuts having' at their lower ends collars as shown on which the frame rests. As the screws are all. of the saine pitch, as shown,y by turning the lifting nuts 37 and 42 in unison the frame may b'e fed up or down with an equal and parallel motion of all its parts. To actuate the lifting nuts in this manner ythe nut 37 is rovided with. a bevel gear 46\ engaged by. a evel pinion 47 on la horizontal shaft 48 journaled on the frame, and at the y other end of the shaft is a `bevel pinion'49 engaging a bevel gear y51 on a cross-shaft 52 eared` at its ends to the lifting nuts .42.: y rotating the shaft 48 the lifting nutsl may all be rotated in funison, the direction of the screw threadsbeingsuch as. to opera'te .in\ f harmony to raise or lowerl the frame. 65 The mechanism'ffrom whichfp'ow'er for the form. controlled by a hand le doublepulleyl .ion 86.. The vpinio performance of the functions above described is derived will now be described. An electric motor 54 is mounted on the frame 34. A belt 55, driven bythe motor, passes about one side of a pulley 56, loosely journaled on a stub shaft 57 on the frame, and then around a second pulley 58 which carries a sleeve 59 (shown in dotted lines in Figf 1 and in trans' verse section in Fig. 1a) journ'aled in a bearing 61 on the frame. -The belt thus operates to rotate the ulleysf56 and 58 in opposite directions'. T e driving shaft `32 by which the saws are rotated is shown as journaled in and-passin through the sleeve 59. To start or stop t eesaws the sleeve 59 and the shaft 324may be connected together or disconnected by a friction clutch 62 of ordinary ver 63.

The mechanism for im arting the slow feeds to the' saws during tile sawin operation is actuated from the driving sha t 32. 'A 64` on the'shaft is connected by a belt as shown in Figs. 1, 2, 3 and 7, with 'a ulley 65 fixed to a shaft 66 journaled on the ame.' A friction disk 67 on the end vof the yshaft 66 .is engaged by' a friction wheel`68,

which is splined to a cross-shaft 69 so that it may be moved along the shaft by a hand lever 71 (Fig. 2) and caused to engage'diiferent parts of the face of the disk 67 to secure different s peed ratios. The shaft 69 carries a bevel imon 72 engaging a gear 73 loosely jou-rna ed on a counter-shaft 7 4 which is jour-l naled on the frame in alinement with the feed screw 36. "By means of a tooth clutch 75 of ordinary form, controlled by a hand lever 76, the gear 73 may be connected at will with the counter-shaft 7 4. Another tooth clutch l77 of ordinary form (Fig. 1) is interposed between the counter-shaft and the feed screw and iscontrolled by ahand lever 78..

When a slow longitudinal feed ofthe carriage is desired the clutch 75 .fis engaged and the clutch 77 is thrown to the right so as to connect the counter-shaft 74 witha sleeve 79 fixed on the end 'of the feed screw 36 and servingas'a bearingfor the shaft 74. The feed screw is then slowly rotated, and the rate of feedlmay be varied by means of the frictional driving mechanism comprising the disk 67 and the wheel 68.

For theslow vertical feed the connected witha pulley 81 on a sliaft 82 con'- nected,--through a friction'disk 83 and a friction wheel 84splined'on .a cross-shaft 85`so that itmay be moved along theshaft by a hand lever 60 (Fig. 3) andmade to engage different arts of the face of the disk 83 to obtain'di erent s eed .ratios of thle slow verticalfeed. The s aft 85 carries a' bevel pinn 86 engages two gears 87 and 88 loosely journaled between two collars 89 on the vertical-feed shaft 48, *andthe gears are rotated constantly in opposite' directions.

A toth clutch 91 of ordinary form is arranged the feed screw 36.

the saws, a rapid actuation or movement is f accomplished through the counter-shaft 74.

. This shaft carries at its left-hand endl a gear 93 engaged by gears 94 and 95 loosely journaled` on the stub-shaft 57 and the shaft 32 res ectively. The gears 94 and 95 carry eac a member of two cone clutches 96 and 97, of which the other membersare carried by the pulleys y56 and 58. A hand lever 98 pivotally `mounted at 99 operates to throw the clutches alternatively into and out of engagement, so that the gear 9 3 and the countershaft 74 may be rotated rapidly in either direction, or may be left' free when the hand lever is in its median .position with both clutches disconnected. I

. When a rapid horizontal movement is desired the hand lever 98 is thrown to one side or the other, and the clutch 77 is thrown to.

the right to connect the counter-shaft 74 and When a rapid vertical movement is desired the clutch 77 is thrown to the left, so as to disconnect the countershaft and the feed screw, and in this position the clutch 77 connects the counter-shaft with a gearx 101 loosely journaled thereon and meshing with a gear 102 fixed on the verti- 'cal-feed shaft 48. During these operations the slow-feed clutches 75 and 91 are' in their non-operative positions, so that the gear 73, for the horizontal slow feed, and the gears 87 and 88 for the vertical slow feed, do not actuate the shafts 74 and 48 respectively, but either rotate idly or remain at rest according vas the saw driving shaft is rotating or not.

By means of the various feeds and adjustments of the machine the saws may be caused to perform a eat variety `of operations. The stone105 1s moved under the machine on a suitable car or carriage 106, and the Asaws are then adjusted to the proper position on the carriage. By means of the quick-feed or moving mechanism 'the saws' are then brought into position to engagethe stone, and the slow-feed mechanism is then thrown into operation to feed the sawsduring the cuttingI operation. It is obvious that for large stones the carriages 106 may be cou led together, or, as shown, theyl may be use independently, as desired. `The saws maybe used either sin ly or together, and may be set to perform up'licate-operations or to participate in a single operation or to erform different operations. When one or oth of.

vthe saws are in operation ina vertical plane both slow-feeds may b'e used together, and therebya cut with an inclined termination may be produced, as in'Fig. 8. yA rabbet or shoulder may be formed, as in Fig. 9, by adjusting the saws on the carriage so that they form an angle with each other and so that their peripheries are close together at the point of cutting. In performing this operation the horizontal feed only is used.

bevel may be formed, as in Fig. 10, -by one saw alone, or -a cornice may be rou'ghed out, as in Fig. 11 by using both saws. By operating both of the saws in vertical planes with one at a higher level than the other, While employing the horizontal feed, 'a chec may be formed and a stone faced on one side-at the same time, as 'in Fig. 12, the saws substantially in the same position as in Fi'g.- 12, a panel may be outlined with one saw, as indicated in elevation in Fig. 13, while at the same time the stone is faced with the othersaw.` In this operation the feeds are pro erly mani ulatedto determine the limits ofp the pane while allowing the lower or facing saw, on account of the lower position, to cut entirely through and out at the end' ofthe stone, as shown.

As the 'driving shaft 32 is of considerable length it is desirable to support it between the carriage and the frame. For this purvpose two hangers, 102 and 103, are slidably sus ended ,from the ways on the frame 3.4, an the hangers are connected b side rods 104 so that when one hanger is dlsplaced by the movement of the carriage in either direction the other hanger is moved to operative position behind the carriage.

In addition` to the features of-construction relating .to ythe general mode of operation of the machine, there are various details of construction whichare novel and useful. The employment of two laterally-located elevating screws lat one end of the frame permits the use of a'central saw-driving shaft at this p'oin't and has the further' advantage of furnishing a firm three-point support for the frame. driving shaft and the slow-feed mechanism 'is such t at the feed stops whenthe rotation of such shaft stops, and 'thus the accidental disconnection of the driving clutch 62 cannot result in damage Ato the machine, as would occur if the feed continued. v

It is obvious that various modifications With The connection `between the sawy may be `made in the construction shown and f v above-particularly described' within the prinmeans for actuating the saw, and mechanism for feeding it in' two directions inthe same plane.
